The easiest way to change your password is to pick up your phone connected to the ooma hub and press the "play" key. It looks like a forward arrow. Alternately, you could call your own number from that same phone. You will be prompted to press 2 if you want to change your options. After doing so, another option to change your pin will be presented. After you change your pin, you can also check your outgoing message and make other setup choices.
